Nu-Calgon 4171-75 Evap Foam No Rinse Evaporator Coil Cleaner, 18 oz. (Pack of 2)

Pack of 2. Evap Foam no rinse is a high performance, heavy duty detergent, specifically formulated with special surfactants and alkaline cleaners that have been developed into a foaming, no-rinse product. The aerosol product can be sprayed either right side up or upside down, and is ideal for use on most coils, but particularly suited for cooling or evaporator coils.

Evap Foam will liquefy dirt, grease, oil, and other residues quickly and easily. 

Since it is fortified with corrosion inhibitors, it is safe for use on metals and other materials. The products fast-breaking foam is completely self-rinsing. 

Simply spray Evap Foam on the coil and the foam will wash the emulsified matter off. The aerosol product is NSF registered for use as a coil cleaner in and around food processing areas, and helps leave the area deodorized with a pleasant lemon scent.

Drections for use:  Turn off or disconnect power to unit being serviced, and remove any heavy or matted soils first. Shake well. Remove cap and point toward surface to be cleaned. 

Thoroughly saturate the targeted area with product. 

Be sure foam evenly covers the entire surface. With this self-rinsing formula, the foam will break and condensation will completely rinse the emulsified material. 

However, you may wipe clean or rinse with water if desired or if using on non-condensation producing coils. For extremely stubborn or heavy deposits, repeat applications may be necessary. Turn on or return power to the unit.
